The hygrometer is a device assembled on the basis of polystyrene or other materials of similar properties. To base mounted two thermometers with scale, psychrometric table, glass feeder, filled with distilled water.
The reservoir of the thermometer under the inscription “moisturizing”. moistened with water from the feeder using a wick.
The method of measuring relative humidity psychrometric humidity sensor is based on the relationship between the humidity and the psychrometric difference – the difference between the readings of “dry” and “moist” thermometers are in thermodynamic equilibrium with the surrounding environment
After removing the thermometer readings and introducing amendments to their statements, determine the difference between the thermometer readings. Then, as indicated by the “dry” readings of the thermometer and the difference of “dry” and “wetted” thermometers determine the relative humidity on a psychrometric table.
